Gravitational lensing is a naturally occurring phenomenon that behaves like as a cosmic telescope, magnifying distant background galaxies that are otherwise beyond our reach. Modeling gravitational lenses can probe the mass distribution of the lensing cluster, predict the location of the distant sources that are blocked by the intervening cluster, and provide a foundation for detailed studies of high redshift sources. This project utilizes a parametric modeling software called Lenstool to model the gravitational lens SDSS J1138+2754, detected in the SDSS's Giant Arcs Survey and imaged using the Hubble Space Telescope. Lenstool produces mass maps describing the mass content within the cluster and the source and image-pair locations.
